Online Mandolin Tuner

Use this free online mandolin tuner to tune your mandolin. This is for the standard GDAE mandolin tuning. For other methods on how to tune your mandolin go to our Mandolin Tuning Methods page. Mandolins have strings that are in pairs, which are tuned to exactly the same note. These pairs of strings create a cool chorus-like effect, very similar to the sound of the 12 string guitar.

ALERT Sorry, your web browser does not support Adobe Flash or does not have it installed. Most Apple products do not support Flash. Please use our HTML5 Mandolin Tuner that will work with almost all modern browsers.

How to use this tuner: Click on the note for the string you want to tune and then turn the tuning pegs on your mandolin to match it up with the note that is being played. For best results adjust the volume on your computer until it has the same volume as your mandolin.

If you want to tune your mandolin using alternate mandolin tunings, check out our new Online Mandolin Tuner which allows you to change the pitch for each string.

Thanks so much. I just love to tune my mandolin with this. I am a Mailman who plays the Mandolin.

The E is sharp about 3 lines on my tuner the other three notes are dead on but the E needs to be adjusted .

The E might take a few secs. It starts flat and levels higher.

Thanks. Works for me. And I didn't break any E strings. I use it for both guitar and mandolin when I can't find my clip-on tuner.
